Only problem is, once they open the gate the entire world will be covered in darkness. Meanwhile, in the afterlife, Mina encounters Izuko, the Guardian of the Gate. Izuko gives her three options: Mina can choose to ascend to heaven and be reborn, she can choose to forever walk the earth as a ghost or she can choose to curse one of the living to death and as a result be cursed to descend to hell. Mina has 12 days to make her choice. - Wikipedia.
